1. From the perspective of psychology, generalization is to abstract and synthesize the common attributes (essential or non essential) of different things, so as to form a daily concept or scientific concept. For example, the fruit, shape, color and taste of various plants are different, but they all grow on plants and have seeds inside. The concept of fruit is formed by combining these two basic attributes. Generalization is a synthesis based on abstraction. Generalization plays an important role in intellectual activities. Without generalization, there is no concept. Without concept, there is no logical thinking. So Rubinstein said, "thinking is done in generalization." The most prominent feature of thinking is generality
generalization is closely related to the transfer of learning. Judd, an American psychologist, believes that generalization is the key to the generation of learning transfer. Only by summarizing his experience and obtaining general principles can learners realize the transfer from one learning situation to another, and "draw inferences from one instance" and "learn from one". In a word, generalization ability is the basic skill of intelligence. The process of children's generalization of knowledge is the process of transforming knowledge structure into cognitive structure, that is, the process of intellectualizing knowledge. Generalization learning is meaning learning and concept learning, so it is very important to cultivate students' generalization ability
generalization can be divided into many levels. Former Soviet psychologist Rubinstein divided generalization into primary "experience generalization" and advanced "theory generalization". A large number of experimental studies show that students are able to carry out primary experience generalization and form primary concepts for familiar things such as beasts, animals, furniture, fruits and vegetables; In particular, the operation of intelligent learning aids in the experiment of learning aids teaching method creates favorable conditions for the development of students' generalization ability. The cultivation of generalization ability is an important content of learning tools teaching method.

2. The power of observation is the window of the eyes. Only by pushing it open can we let in the beauty of life; Generalization is the banner of life. Only by waving it can the future road be orderly; Memory is the projector of the mind. Using it, you can make the film of knowledge vivid;

(1) intelligence and ability: talent is outstanding, talent is sufficient, talent is lack of the ability to adapt to circumstances, and talent (wisdom) can only be understood and allowed. It also refers to people with intelligence and ability: select talents | recruit talents from all over the world

(2) adverbs. Rigid energy; Just now can: he came, I can go

(3) people's ability to understand and transform the world. It is related to physiological quality, but mainly formed and developed in social practice. Talent is closely related to knowledge, but it mainly refers to the ability to use knowledge in practice

4. KTPA is a unit of weight, which is "100 tons"

kn is the unit of force, which is called kn or kn
force
(1) the concept of force
force is an interaction between objects, which proces two effects on objects. One is to make the object proce acceleration, which is called dynamic effect; The other is to deform the object, which is called static effect. Force is the interaction between objects, so force can not exist alone without objects. Force is a vector, to determine a force, we must know its size, direction and action point, namely the three elements of force
(2) unit of force
in the international system of units (SI), the unit of measurement of force is Newton, abbreviated as cow, and the symbol is n. Newton is a derived unit (non basic unit), which is defined as: the force acting on a 1kg object to proce 1m / S ^ 2 acceleration is 1n, that is, 1n = 1kg · M / S ^ 2, and the dimension is [LMS ^ - 2]
the commonly used measurement unit of force is: Micro bull μ N) The conversion relationship is: 1MN = 1 × 10^3kN 1kN＝1 × 10^3N 1N＝1 × 10^3mN 1mN＝1 × 10^3 μ N

2.2kW gasoline generator is about 3 horsepower

2.2 ÷ 0.735 ≈ 3 HP

< p class = "ikqb_ image_ Horsepower is a commonly used unit for measuring power in engineering technology, which was proposed by James Watt. One horsepower is about 735 watts. Generally refers to metric horsepower rather than British horsepower

1 HP is equal to 75 KGF in 1 second; The work per meter is also equal to 0.735 kilowatts, or metric horsepower. One British horsepower equals 550 feet; LBF / S is equal to 76 KGF; M / s, or 0.746 kW. In China's legal units of measurement, the unit of power is watt

"Horsepower" is a unit of power, which is often written on diesel engines and steam turbines. How does horsepower come about

more than 200 years ago, engineers manufactured the first batch of improved steam engines in the world according to the design of British James Watt. A brewery ordered a pump instead of horses. The brewer wanted to make sure that the steam engine was as efficient as a horse. So he chose the strongest horse from his herd and let it work for eight hours without feet. He calculated that more than two million kilograms of water had been drawn ring this period. After conversion: a horse can increase 75 kg of water by 1 meter per second, that is, 1 horsepower = 75 KGM / s. After that, people took it as the power unit of power machinery, and it has been used until today

Metric horsepower / metric horsepower is also called metric horsepower. Its regulation is completely artificial, and it takes a value very close to the British horsepower. It is stipulated that 1 metric horsepower is the work of 75 KGF · m in 1 second. That is: 1 metric horsepower = 75 KGF · M / S = 735 watts

British horsepower the concept of horsepower is named by steam engine improver James Watt, which is used to express the power of his steam engine relative to the pulling force of horses. It is defined as "the power of a horse that can pull 33000 pounds and walk at 1 foot per minute", and uses watt (W) or kilowatt (kw) as the standard unit

British horsepower is used in Britain, the United States and other countries. One British horsepower equals 550 ft. lbs. and 745. 7 watts

in the late 18th century, British physicist watt (1736-1819) in order to determine the power of a newly manufactured steam engine, he defined horsepower as the work of lifting a 1000 pound weight by 33 feet in one minute, which is British horsepower, expressed by the letter HP
more vividly, an instant burst (such as a nk) can reach 2 horsepower. A common air conditioner in our daily life is horsepower. One horsepower of the air conditioner is enough for a bedroom, and the horsepower of the microwave oven and electric kettle is even as high as two horsepower

detailed explanation
general ability
refers to the ability shown in different activities, such as imagination, memory, observation, analysis, abstract generalization, etc. Abstract generalization power is the core of general ability and the basis of thinking. Usually, intelligence refers to general ability. We usually complete all kinds of activities are inseparable from the use of these abilities
special ability
refers to the ability shown in some professional activities. It is an important condition for the successful completion of certain professional activities. For example: the painter color identification ability, image memory ability; Musicians' ability to distinguish melody, music representation and feel music rhythm are special abilities
imitation ability

For example, children imitate their parents' words and expressions in the family; Imitate actor's behavior and dress from TV play; From the calligraphy and painting on the imitation of previous works of art. Imitation is not only reflected in the same reaction immediately after observing other people's behavior, but also in some delayed behavioral reactions. Imitation is an important learning ability possessed by both animals and human beings
creativity
refers to the ability to proce new ideas and new procts. Animals can imitate, but rarely create. Imitation can only solve problems in a ready-made way, while creativity provides new ways to solve problems. A creative person can often get rid of the shackles of specific perceptual situation, thinking set, traditional ideas and habitual forces, find new connections and relations in the things and phenomena he is used to, put forward new ideas and proce new procts.
